Thus the wavelength of a 100 MHz electromagnetic (radio) wave is about: 3Ã10 8 m/s divided by 10 8 Hz = 3 metres. The wavelength of visible light ranges from deep red, roughly 700 nm, to violet, roughly 400 nm (for other examples, see electromagnetic spectrum).
Mumble, Putting a modem to bridge mode just makes it dumb, it will let anything pass though, though when hits the Router it will then get routed to where needs be. The option is really up to yourself. Once advantage would be, only the Router will need to be setup accordingly, as the modem just passes internet traffic.
The new FT1DR provides three digital modes (V/D mode, Voice FR mode, Data FR mode) and a Analog mode: Â· V/D mode is Voice and Data communication in the same time frame. This mode enables the transceiver to send voice data with GPS position data and ID data in the same time frame.Also, this mode can pass the voice data with strong error correction data to stabilize the digital communication.. Voice FR Mode (Voice Full Rate Mode) This mode uses the entire 12.5 kHz bandwidth to transmit digital voice data. The larger voice data size allows voice communication with high sound quality. Use this mode for pleasing sound quality communication between amateur radio friends.
